lambda=?
c=299,792,458
f=2x10to the 12th Hz
lambda=c/f
how do I solve this?

Sagot :

[tex]\lambda=\frac{c}{f}\\\\ c=299729458\frac{m}{s}\approx3*10^{8}\frac{m}{s}\\\\ f=2*10^{12}Hz=2*10^{12}\frac{1}{s}\\\\ \lambda=\frac{3*10^{8}\frac{m}{s}}{2*10^{12}\frac{1}{s}}=1,5*10^{8-12}*\frac{m}{s}*s=1,5*10^{-4}m[/tex]
